Abstract

The present invention relates to a cosmetic composition containing a unique polymer blend, which includes: (a) a first polymeric film-former having a first glass transition temperature ranging from about −20° C. to about 0° C.; (b) a second polymeric film-former having a second glass transition temperature that is at least 50° C. higher than the first glass transition temperature; and (c) a third cross-linked polymeric film-former. The cosmetic composition of the present invention can be applied to human skin or keratinous fibers for forming a film thereon with exceptionally long wearability, reduced flaking and smudge properties, and good removability by warm water.

Claims

exact text as granted — not AI-modified
1 . A cosmetic composition comprising:
 (a) a first polymeric film-former having a first glass transition temperature ranging from about −20° C. to about 0° C.;   (b) a second polymeric film-former having a second glass transition temperature that is at least 50° C. higher than the first glass transition temperature; and   (c) a third cross-linked polymeric film-former.   
   
   
       2 . The cosmetic composition of  claim 1 , wherein the first polymeric film-former comprises one or more water-soluble or water-dispersible acrylates copolymers comprising one or more monomers selected from the group consisting of C 1 -C 8  alkyl acrylates, C 1 -C 8  alkyl methacrylates, C 1 -C 4  alkoxy acrylates, C 1 -C 4  alkoxy methacrylates, and combinations thereof. 
   
   
       3 . The cosmetic composition of  claim 2 , wherein the first polymeric film-former comprises an acrylates/octyl acrylate copolymer. 
   
   
       4 . The cosmetic composition of  claim 3 , wherein the acrylates/octyl acrylate copolymer is present in an amount ranging from about 5% to about 15% by total weight of said cosmetic composition. 
   
   
       5 . The cosmetic composition of  claim 3 , wherein the first polymeric film-former further comprises an ethyl acrylate/methyl methacrylate/methacrylic acid copolymer. 
   
   
       6 . The cosmetic composition of  claim 5 , wherein the ethyl acrylate/methyl methacrylate/methacrylic acid copolymer is present in an amount ranging from about 0.1% to about 5% by total weight of said cosmetic composition. 
   
   
       7 . The cosmetic composition of  claim 1 , wherein the second polymeric film-former comprises an acrylates copolymer having one or more monomers selected from the group consisting of acrylates, alkyl acrylates, methacrylates, alkyl methacrylates, hydroxyesters acrylates, and combinations thereof. 
   
   
       8 . The cosmetic composition of  claim 7 , wherein the second polymeric film-former comprises a mixture of the acrylates copolymer with a vinyl polymer. 
   
   
       9 . The cosmetic composition of  claim 7 , wherein the second polymeric film-former comprises an acrylates/hydroxyesters acrylates copolymer. 
   
   
       10 . The cosmetic composition of  claim 9 , wherein the second polymeric film-former comprises a mixture of the acrylates/hydroxyesters acrylates copolymer with polyvinyl acetate. 
   
   
       11 . The cosmetic composition of  claim 10 , wherein the acrylates/hydroxyesters acrylates copolymer is present in an amount ranging from about 0.05% to about 2%, and the polyvinyl acetate is present in an amount ranging from about 0.1% to about 5%, by total weight of said cosmetic composition. 
   
   
       12 . The cosmetic composition of  claim 1 , wherein the third cross-linked polymeric film-former comprises a taurate crosspolymer. 
   
   
       13 . The cosmetic composition of  claim 12 , wherein the taurate crosspolymer comprises acryloyl dimethyl taurate monomers and one or more additional monomers selected from the group consisting of styrene, acrylic acid, methacrylic acid, vinyl chloride, vinyl acetate, vinyl pyrrolidone, isoprene, vinyl alcohol, vinyl methylether, chloro-styrene, dialkylamino-styrene, maleic acid, acrylamide, methacrylamide, and combinations thereof. 
   
   
       14 . The cosmetic composition of  claim 12 , wherein the taurate crosspolymer is an acryloyl dimethyltaurate/vinyl pyrrolidone crosspolymer or an acryloyl dimethyltaurate/beheneth-25 methacrylate crosspolymer. 
   
   
       15 . The cosmetic composition of  claim 1 , wherein the third cross-linked polymeric film-former comprises an acryates/C 10 -C 30  alkyl acrylate crosspolymer. 
   
   
       16 . The cosmetic composition of  claim 15 , wherein the acrylates/C 10 -C 30  alky acrylate crosspolymer is cross-linked by a cross-linking agent selected from the group consisting of allyl ether of sucrose and allyl ether of pentaerythritol. 
   
   
       17 . The cosmetic composition of  claim 1 , wherein the third cross-linked polymeric film-former is present in an amount ranging from about 0.01% to about 2% by total weight of said cosmetic composition. 
   
   
       18 . The cosmetic composition of  claim 1 , which comprises an oil-in-water emulsion, and wherein said first polymeric film-former, said second polymeric film-former, and said third cross-linked polymeric film former are dispersed in an aqueous phase of said oil-in-water emulsion. 
   
   
       19 . The cosmetic composition of  claim 18 , further comprising one or more waxes in an oil phase of said oil-in-water emulsion. 
   
   
       20 . A cosmetic composition comprising:
 (a) from about 5 wt % to about 15 wt % of an acrylates/octyl acrylate copolymer;   (b) from about 0.1 wt % to about 5 wt % of an ethyl acrylate/methyl methacrylate/methacrylic acid copolymer;   (c) from about 0.05 wt % to about 2 wt % of an acrylates/hydroxyesters acrylates copolymer;   (d) from about 0.1 wt % to about 5 wt % of polyvinyl acetate; and   (e) from about 0.01 wt % to about 2 wt % of a cross-linked polymeric film-former selected from the group consisting of a taurate crosspolymer or an acryates/C 10 -C 30  alkyl acrylate crosspolymer.
